Radial line development - Round Reducer, fabrication

[@BouncyThrone]

A few years ago, I got into HVAC and built ductwork, installed, service, etc, and thought I knew something.. But recently I started at an industrial fab shop/structural/HVAC company. We build all our our own ductwork and fittings before we install, instead of picking up fittings at the supply house like I was used to. This all blows my mind. Your instruction videos are insane! They've helped me to wrap my mind around some of this stuff, and have helped my understanding quite a bit. Thank you for taking the time to share your knowledge..

Thanks Roy, Im happy to hear your comment. It does take many hours on the tools and different jobsites to get half decent with this stuff 😀

This helped lots I had the material cut but didn't turn in the roll press and that's why it didn't end up rolled correctly thanks for the advice and instruction

[@sheetmetalwork]

I’m happy to hear that you figured it out. 👍

[@jesseramos714]

I've watched your offset video as well , very good material!

[@sheetmetalwork]

Thanks for taking the time to post your positive feedback. Appreciated!

[@777smitty4]

Very good video I’m trying to refresh my old apprentice day . If I remember correctly you have to triangulate the height to compensate for offset but I don’t remember exactly how to do that

[@sheetmetalwork]

@@777smitty4 maybe the beginning of this video will refresh your memory kzbin.info/www/bejne/Z6SWfqmfd6yFqcUsi=Db7RleHG3L1pSYqu. Let me know if it helped.

Excelente trabajo amigo, gracias por compartir tus conocimientos. 👉👉👉

[@sheetmetalwork]

Ha sido mucho trabajo, pero divertido al mismo tiempo, planeo producir más en los próximos meses.

[@sheetmetalwork]

Estoy usando una aplicación de traducción porque realmente no entiendo completamente el español. Ha sido divertido charlar contigo y, por cierto, soy de Moncton, New Brunswick, Canadá, que se encuentra en el lado este o lo que se llama Atlántico de Canadá. ¿Y tú de qué parte de México eres?

Happy to help.

Is there a way to make complete reducer -collars and net pattern out of one sheet of metal? So that it only has one seam? I would like to try build a cyclone but it wont work with this much things sticking out,inside needs to be as smooth as possible .Any ideas? Also there is another way ,when you inputed 6"x pi =18.8496 -you can divide 18.8496 by any number that gives you best result that is easiest to setup ,draw the line of that distance on paper and adjust your calipers with it.Then you just go around 6" circumference by that number. For easy of understanding lets say that instead of 18.8496 you got 12" -its easy to divide it by 4 so you would take 4" in calipers and go 3 times around circumference.

[@sheetmetalwork]

The only thing I can think of is to use a Shrinker/Stretcher, but the collar lengths must be kept short.

Thank you sir for sharing your knowledge👌👍

[@sheetmetalwork]

Thanks for the comment

[@Oxatolla]

Hi Duane, how tall should a 24" to 20" round reducer be? Thanks.

[@sheetmetalwork]

depends if it's for air or material handling. IMO, you could keep this one 8 to 14" but you might want to check with SMACNA standards
